Basic Data

This part of the window serves to introduce basic parameters of soils - unit weight, angle of internal friction and cohesion. The particular values are obtained from geotechnical survey or from laboratory experiments. If these data are not available, it is possible to exploit built-in database of soils, which contains values of selected characteristics of soils. The characteristics of rocks are not listed in the database built, these parameters must be defined manually. Approximate parameters of rocks are presented in the theoretical part of the Help herein.

analysis of foundation on rock subgrade: for this analysis method program defines angle of internal friction of rockφ, compressive strengthσc, coeficient of damage of rockD, coefficient of structural strengthmi and Geological Strength Index.

The associated theory is described in detail in chapter "Analysis of bearing capacity of foundation".
